What is SHA-256?
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that generates a nearly unique 256-bit (32-byte) hash from any input data. This hash acts as a digital fingerprint, meaning even a small change to the input will result in a drastically different hash value. It's primarily used for verifying data integrity, digital signatures, and password storage due to its one-way nature, making it computationally infeasible to reverse the process and derive the original input from the hash.

SHA-256: common questions
Can I learn SHA-256 in Hindi?
This lesson is written in English. Once you sign in, open it in the interactive course and ask the AI tutor to explain SHA-256 in Hindi or Hinglish. The tutor answers from this lesson’s own text, so it stays on the syllabus, and it runs on your own Google, OpenAI or Anthropic key.
Is this SHA-256 tutorial for beginners?
It is lesson 71 of 93 in the free DevSecOps roadmap, in stage 17, Enterprise Operations. If you are new to DevSecOps, start from stage 1 and come back here in order; if you already know the earlier stages, this lesson stands on its own.
